Abstract: At present, Many systems of manufacture, adaption and making which are made up of multiple robots mainly have been used in modern production windly, In order to adapt the requirements of the rexibile and agile manufactures, it is necessary to research multi-robot system. The authors, based on the experience of resesrching the multi robot coordination, view a multi-robot system as a whole, and research its whole behavior and architecture with the system method. This paper rely on the multi-agent system as the theoretics fundament, network communication and distributed database as the technical fundament, propose the research contents of realizing the distribution, autonomy and cooperation in multi-robot system and key techniques must be sloved, then introduce our research work in this field.
